Above, the cursor is the
two white boxes. The panels within the cursor are joined together.

Press the "A" button, and
the two panels within the cursor switch left and right, taking each other's
place. This aligns a column of Heart Panels.

Because three matching
panels in a row were touching, they vanished. Pieces above the vanished
panels fall.

Skill Chain

When more than 4 panels vanish
in one move, this is called a "Skill Chain". It doesn't matter if
two sets of panels are different colours--it still counts towards overall
number of vanished panels in one turn.

Active Chain

Switch the Green
and Yellow
Panels, causing the Green
Panel column to vanish. Now, the Violet
Panel begins to fall. You have only an instant to move the Violet
Panel on the right over! The Violet
Panel above will fall, creating a column of three Violet
Panel that will vanish. That's an "Active Chain".
